<p>The anti-jackknifing system includes an abutment apparatus (Figs. 1-4, 7, 8) and electrical (Fig. 5) and hydraulic (Fig. 6) controls provide system control for limiting relative angular movement between an articulated tractor (10) and trailer (20). A cylinder (36) mounted within a rigid frame (23) is mounted by a mounting bar (25) to a forward beam member (22) of the trailer (20) for moving an abutment element (28, 128) into and out of an engagement zone within the longitudinal V-slot (17) of the fifth wheel (14). The abutment element in position on a rotational swing of the articulated vehicle is contacted by ears (18) of the V-slot, where due to the structure of the apparatus, the further rotational movement may be arrested or controlled to permit adjustment of the rotational limit of further angular movement under control of the driver. The system can be adjusted and controlled to permit adaption of the moving vehicle to various road and rig movement conditions, acting to prevent dangerous jackknifing from occurring.</p> |
